Jada Pinkett Smith's hair loss which strikes 20 million women in menopause Jada Pinkett Smith announced Monday that struggles with hair loss The star has cut her hair short and taken to wearing turbans About half of all women suffer some degree of hair loss before age 50 Hormonal changes in the approach to and during menopause shorten the growth cycle of hair while higher relative levels of other hormones stop growth Jada Pinkett Smith has revealed she struggles with hair loss, like 21 million women in the US. At 46, Pinkett says she does not know the cause of her hair loss, but has embraced it with a short asymmetrical bob and turbans. Hair loss can come as the result of thyroid disorders, anemia, polysistic ovary syndrome or the autoimmune disease alopecia, as some have speculated Pinkett Smith has. But for many women, hair loss is simply a part of the aging process and onset of menopause. Thick, dark, waist-length hair has been one of Pinkett Smith's signature looks. But since she started noticing her hair thinning - even coming out in fistfuls in

the shower at times - Pinkett Smith has just cut her hair shorter and shorter, and kept her hair loss under (literal) wraps. Finally on Monday Pinkett Smith spoke out on her Facebook show Red Table Talk, which she hosts with her mother and 17-year-old daughter Willow Smith, about her hair loss. The star, who is also mother to actor 19-year-old Jaden Smith and wife to actor Will Smith, has kept quiet about about her hair. 'I haven't talked about it, it's not easy to talk about, but I am going to talk about it,' the Girls Trip star said. 'I've been getting a lot of questions about why I've been wearing this turban,' Pinkett Smith said of the beautiful pink and yellow head wrap she had donned for the show. 'Well, I've been having issues with hair loss,' she added. She is far from alone. About half of all women suffer some hair loss before the age of 50. Many men lose hair or bald as well, but the age-related causes are quite different. Watch Video Below
